Earnings Per Share Calculator
Earnings Per Share Calculator
Estimate basic EPS, diluted EPS, and dilution impact from net income, preferred dividends, weighted average common shares, and potential dilutive shares. Use filings and accounting notes for official reported EPS.
Inputs
Use net income from the same period as the share count.
Subtract preferred dividends to estimate earnings available to common shareholders.
Use an estimate for options, warrants, or convertible securities only when they are dilutive.
Results
Basic EPS
$2.40
Diluted EPS
$2.2857
Breakdown
Educational estimate only. Official EPS in company filings may use detailed accounting rules, continuing operations presentation, anti-dilution tests, two-class method rules, and weighted share calculations not modeled here.
EPS Formula Guide
| Metric | Formula | Use for | Main caution |
|---|---|---|---|
| Basic EPS | (Net income - preferred dividends) / weighted average common shares | Simple per-share profitability before potential dilution | Can overstate per-share earnings when options or convertibles are meaningful |
| Diluted EPS | (Net income - preferred dividends) / (weighted average shares + dilutive shares) | More conservative view when potential common shares may dilute earnings | Actual GAAP diluted EPS can require security-specific rules and anti-dilution tests |
| Dilution impact | Basic EPS - diluted EPS | Shows how much potential share issuance lowers per-share earnings | Depends on whether potential shares are truly dilutive in the reporting period |
Method and Worked Example
Direct answer: basic EPS equals earnings available to common shareholders divided by weighted average common shares. Diluted EPS uses a larger share count when potential common shares would dilute earnings.
Worked example: if net income is $1,200,000, preferred dividends are $0, weighted average common shares are 500,000, and potential dilutive shares are 25,000, basic EPS is $2.40 and diluted EPS is about $2.2857. The dilution impact is about $0.1143 per share.

FAQ
What is earnings per share?
Earnings per share, or EPS, is a company profitability metric that divides earnings available to common shareholders by weighted average common shares outstanding.
What is the basic EPS formula?
Basic EPS equals net income minus preferred dividends, divided by weighted average common shares outstanding.
What is diluted EPS?
Diluted EPS includes the effect of potential common shares such as options, warrants, or convertible securities when they would reduce EPS.
Is EPS enough to value a stock?
No. EPS is one input. Investors usually compare EPS with revenue quality, cash flow, debt, share count changes, industry peers, and the company filings.

Frequently Asked Questions
What is EPS (Earnings Per Share) and how do I calculate basic vs diluted EPS?
Basic EPS equals earnings available to common shareholders divided by weighted average common shares. Diluted EPS uses a larger share count when potential common shares such as options, warrants, or convertibles would reduce EPS. Official reported EPS can require detailed accounting rules, so use company filings for final numbers.
How do I use EPS to evaluate stock value and what is a good P/E ratio?
EPS is one input in valuation. Investors often compare EPS with price, revenue quality, cash flow, debt, margins, share count trends, and peer companies. This calculator does not decide whether a stock is cheap or expensive.
What inputs do I need?
Use net income, preferred dividends, weighted average common shares, and estimated dilutive shares from the same reporting period. These figures are commonly found in a company income statement, EPS note, or annual and quarterly filings.
Why might official diluted EPS differ from this estimate?
Official diluted EPS can involve anti-dilution tests, weighted timing, continuing operations presentation, two-class method rules, and security-specific accounting treatment. This page is a simplified educational calculator.
Should I use basic EPS or diluted EPS?
Basic EPS is useful for a simple per-share profitability view. Diluted EPS is often more conservative when potential common shares could reduce per-share earnings. Public company filings commonly present both when applicable.
Is EPS a recommendation to buy or sell?
No. EPS is an accounting and analysis metric, not an investment recommendation. Review audited filings, business quality, cash flow, risk factors, valuation, and your own financial situation before making decisions.
How do stock splits affect EPS?
Stock splits change the number of shares used in per-share calculations, so historical EPS is normally adjusted for comparability. Always compare split-adjusted EPS figures from reliable filing or data sources.
